What is a reason for manual diff settings? CKPool VarDiff works like a charm. Do not change anything and just mine. 1042 is start value and it will be automatically adjusted within 10-20 minutes.
I am sure CKPool handles vardiff very well, just seems Ant s2s does not, and tries to throw a fit with vardiff at some point, no idea why though..
Oh ok I see. Lowest Ant I have is S3.. 900-950-1000 is ok for 1 TH/s miner IMO.
